Hi Gang, Its seems in in a quandry. My pool passes OCLT and is crystal clear, however I have persistent 1ppm CC. I break it during the day w/ the sun on the pool, but overnight it comes back. I don’t lose any chlorine overnight. Could it be the high winds and pollen blasting my pool all day...

My pool is 3.5 years old. I noticed my pool seemed to be having problems keeping the chlorine up in the pool. I was running my generator at 90 percent and was still seeing my levels slowly drop. To make sure it wasn’t something in my pool, I did a OCLT (overnight chlorine loss test) and...

Hello, So I've been reading this thread: https://www.troublefreepool.com/threads/2129-Ascorbic-Treatment-to-rid-Pool-of-metal-stains It states in there not to shock your pool for a couple weeks. Is there some flavor of this treatment I can use when I'm OPENING my pool? I figure I probably...

Hey Gang, At the request of another forum member I'm posting a new thread. Last year I had what I'm pretty sure was mustard Algae. I discovered this at the end of last season, trusted the pool store (bad move I know), added some Yellow Treat algaecide (89% sodium bromine), and proceeded to...

Duraleigh, this is pretty much what mine looks like too (from the copper/algaecide thread). Except mine gathers along some of the bottom seam of the liner between the floor and the wall. I never have it in splotches i the middle like the OP does. I did spin my eyeballs to change the flow of...

As prompted by a Mod, I've started a new thread regarding the above. Using this as my backdrop: http://www.troublefreepool.com/content/215-FAS-DPD-Chlorine-Test and making special note of the last line of the page - The precision of the measurement is plus or minus one drop when up to 10...

Hey Gang, I'm debating my wisdom/choice of going w/ a sand filter vs. a cartridge filter. Reason being is all the water/money I'm wasting backwashing into the woods; especially when I'm doing a SLAM. I'm really wondering if I could have done myself a favor by opting for a cartridge filter...

Hey Gang, So I am now in the process of bringing my pool down from mustard algae shock level. I passed a OCLT and ran my pool for 24 hours at MA shock as per the directions on this forum. I've thrown away foam pool toys and soaked material swim floats in my slop sink filled with water and...

Having passed my OCLT (FINALLY) I'm prepared to head up to Mustard Shock level. I'll get this done by 9AM today. My issue now is I expect heavy rain/thunderstorms to roll in later tonight around 11PM - 1AM. If I carry my Mustard Shock level through to this event, will it mess me up if I get a...

I've reviewed this page: http://www.troublefreepool.com/content/215-FAS-DPD-Chlorine-Test I have two questions. Is it necessary to swirl the entire time if you know your chlorine level is high? For instance a SHOCK chlorine level of 30 requires 60 drops. When undergoing my FAS-DPD test in...

Hey Gang, I was wondering if you guys had any advice. I've observed weak flow from my return jets, and dead spots on the more aggresively curved areas of the pool. The following is my pool: Red circles are my skimmers (alpha / beta) and floor drains. Green circles are my returns. Not...

FC: 7.5 CC: 0 TA: 120 Ph: 7.2 CYA: 70-80 This morning I went out to do my weekly pool maintenance. I found a small amount of green algae on the wall of my swimout steps. My water is crystal clear and my chlorine levels are above the recommended TFP levels. My pool is irregular...

Hey Gang, So I just wanted to post something to thank all of our senior posters for their knowledge/wisdom in pool chemistry/maintenance. I've been a follower of this forum since last year; dutifully following the advice and principles found here. When I closed my pool last year it was right...

Given I have a SWG which only makes chlorine when its on, what time of day should I be doing my full battery of tests? If I test at the end of a swim day, won't I get skewed results given bather load and sun? If I test at the beginning of the day, my SWG hasn't been running all night making...

So, another day another lesson learned. I was going through the pool chemicals that my pool installer left and discovered a quart of Poly 60. So, upon reading the instructions I dosed the pool with the initial/startup dosage on the high side. Noting it is a good algae preventer and mild...

Hey Gang, My pool has 10 returns; 6 in the pool and 2 each in the steps and swim-out. My pool has 2 skimmers on opposite sides of the pool, and 2 main floor drains. My steps and swim-out jets are valved such that I can shut them off in favor of the pool jets, or vice versa. My skimmers and...

Just introducing myself. Well met, all of you. I have about 2 years of pool experience with a AGP. Had a 24' round w/ a DE filter on it. This year we installed a 42' free form pool. Vinyl liner, sand filter, SWG, heat pump. We love it !!! I really enjoy reading TFP as I have a...

Hey Gang, Long time lurker, first post here. I've learned a great deal from all of you so before I ask my question, first off THANK YOU !!! Okay, so this is where I'm at. pH - 7.5 TC - 4.0 FC - 4.0 TA - 100 CYA - 70-75 (hard to say for sure looking for the black dot at the bottom of the test...
